The smallest structural and functional unity anything is made of.
Atom
The tool used to order and sort elements by their number of protons/electrons and energy levels.
This type of bond is characterized by an equal sharing of electrons.
This category of elements has one valence electron and is particularly reactive.
Alkali Metals
Subatomic particle with a positive charge.
Proton
This is the number that tells the number of protons/electrons and atom has.
Atomic number
This type of bond is characterized by an unequal sharing of electrons.
Ionic
This category of elements is categorized by their ability to bond easily with other elements, and being gasses at room temperature.
Reactive non-metals
Subatomic particle with a neutral charge.
Neutron
This is the number that tells the general weight of an atom and helps determine the number of neutrons.
This type of bond occurs between two metals.
Metallic
This category of elements is characterized by it's conductivity, stability, how ductile it's elements are, and being the largest category.
Transition metals
Subatomic particle with a negative charge.
Electron
"Groups" categorize elements by this shared characteristic.
Valence electrons
This type of bond occurs between a metal and a non-metal.
Ionic
This category of elements is classified by it's stability, having a full valence shell across the entire category, as well as it's relation to the queen farting.
Noble gasses.
This is the subatomic particle shared during bonding.
Electron
"Periods" categorize elements by this shared characteristic.
Energy levels
This type of bond occurs between two non-metals.
This category of elements is characterized by several of the elements being radioactive, as well as all elements in the category behaving like "Lanthanum".
